I just updated my local tree (branch 0.94, SVN r1435317) and I see
these spurious exceptions in the HBase shell:

$ COMPRESSION=LZO HBASE_HOME=~/src/hbase ./src/create_table.sh
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell

I don't have any local changes.  Anyone else seeing this?  It doesn't
seem to impact functionality (i.e. my table was created properly).

Thanks for reporting this, Benoit.
Here is the call:

          Threads.sleep(1);
Here is the method to be called:

  public static void sleep(long millis) {

Notice the mismatch in argument types: 1 being integer and millis being
long.

Cheers

I suspect this is a different problem. Java will happily cast an int to a long where needed.
Does  mvn clean install  fix this? If not, let's file a jira.

This error is strange.

The sleep method is there  in Threads for a long time now. Ok it was
(int millis) before, and it's (long millis) now but should not do such
a difference.

tsuna, how is your setup configured? Do you run KZ locally? Or
standalone? What jars do you have for HBase and ZK?

It seems your ZooKeeperWatcher is loading a version of Threads which
doesn't have the sleep methode. Sleep method appears in the class in
April 2010... Do you have an old installation of the application
somewhere?
